You're not specific enough. What would be semantics of such wrapper?

The C function I'm trying to wrap takes a function pointer which is essentially a delegate, but not quite:

ErrorEnum function(Struct* s, void function(Struct*, ErrorEnum status, void *userData) callback, void *userData, uint flags) SomeAPIaddCallback;

I want to make it a member function of a wrapping struct so I can call it like

MyStruct ms = ...

ms.addCallback((ErrorEnum ee) { ... });

instead of

SomeAPIaddCallback(ms.s,(Struct*, ErrorEnum status, void *userData) { ... } /*doesn't become a delegate */,null,0);

I'm not sure how to do it.
